A purpose of this study is as follows.1.We clarify a production process of drawings after Meiji period.2.We grasp a characteristic of materials of drawings and grasp a symptom of the deterioration damages.3.We elucidate a cause of deterioration of drawings and think about a method of the save processing.The drawing after Meiji period remaining in Japan was drawn with a new materials. In other words new paper, materials for a new record, new expression technique have been taken in. It begins to the thing which those most use the materials which foreigner engineers invited by Meiji government ordered from the mother country and taught technology to. They change to domestic special paper, aqueous dye, a composition color before long. In a history document of drawings of these days, there are many a remarkable change of color and things looked at of a deterioration symptom. However, measures of save processing are late. The cause is because grasp of those deterioration symptoms and analysis of material do not advance. In this study, we investigated a deterioration invitation of a coloring drawing. In the investigation, we tried that we took in new technique such as measuring the colors and surface observation. Furthermore, we examined deterioration promotion to examine save nature of tracing paper used for a drawing well. And we compared it with paper of other kinds. A direction of a future study pushes forward comparison analysis more and wants to push forward examination of a save disposal of drawings method.
